Punish the people who act.

Seriously, think about the fear here. That someone's trivial to ignore tacky political statement causes what problem? That it causes a fight to erupt? Arrest the person who actually starts the fight.

Do not police the actions of reasonable people just because they might upset unreasonable people. This is absolutely insane! You are just creating a world of Karens and crazy people by enabling them. The people that should get in trouble are the ones who start a fight.

FFS we're talking about a device's name. How often do you even see other device's names? Are you just staring at the WiFi and Bluetooth broadcasts all day? That's mental! You only see it when you switch to the plane's WiFi and then it is done. Over. You don't have to see it again. Anyone that is upset enough to start a fight over such a little thing should absolutely be arrested because they are clearly going to start a fight over some other absolutely bullshit and arbitrary thing. That's a person that is looking for a reason to be upset. That is a person looking for a reason to be angry. That is a person looking for a reason to start a fight. That is a person who is mentally insane.
